Students have homework tonight and it is the same homework they had last week, E63 1-5. The goal is that students will understand the questions better and improve their grade by demonstrating that they have learned the material. The homework is due at the start of class in the morning.
Today we reviewed heat energy transfer and kinetic and potential energy by watching on Youtube; Eureka 24, 27 and 29 and then a clip of Hoodwinked which shows potential and kinetic energy. We also studied thermal expansion by placing a balloon in cold water. We observed that the balloon shrunk. Then the students came forward and placed the cold balloon in warm water. They could feel the balloon expand as it warmed up. Students were told that this is called thermal expansion.
